Hey y'all, been checking around on this site for a while, never registered

I'm making a poster for an upcoming record fair I'm putting together and I always enjoy mixing my media. The poster depicts a jungle explorer amazed at a 45 he's found, and my hopes were to have him coming under attack by tiki mask-wearing natives. I had all these images in my head and thought for sure my record collection would come through, but it hasn't, and neither has the internet. I've found cartoons, sure, I've found stationary masks and moais but I want action! Closest I've come is blurry guys in the background of Yma Sumac's Legend of Jivaro, or maybe Augie Colon's Sophisticated Savage. I might be able to get away with paintings but, for instance, Shag's work is a little too stylized.

I figure y'all are probably the best place to turn on this. Any ideas? I might be able to get away with drawing their bodies if I can at least get some good masks, but as this is a record fair I'd prefer it if they were specifically taken from LP covers.
